Supermarket Diesel Passat B6 2.0 TDi BKP Engine Poor Power Lack of power

**woody80uk** · 15-02-2012,08:27 PM

Has anyone experienced lack of power from setting off. Ive got a 2.0tdi sport 140bhp and the last few months I noticed the "take off power" was getting worse. I usually fill up at Tesco, I decided to use BP as Tesco was busy, after a few miles my car became alive again.

Has anyone else had a similar problem?

Never experienced this. I fill up at supermarket filling stations 75% of the time. Thought that all fuel came from pretty much the same refinery.

Try shell v power diesel, it is very expensive but if you add 10 litres of it then take it for a spin on the motorway. See if that works, if not then add normal shell diesel, then add injector cleaner redex or millers.

Hopefully that should help.

Check the pump at the supermarket while filling up at Morrissons i noticed they dilute their diesel with biodiesel( small print on pump), mine used to smoke like mad when i put my foot down, changed to shell and after every four or five fill ups i put in the V power runs a treat, no smoke and runs great.

That is interesting - I filled up at Morrisons in Berwick on my way back from Edinburgh a couple of weeks ago, and I've had a good few lumpy, smoky starts (there was a right cloud this morning), and a good few clouds of reek when using the loud pedal. I did notice the 7% of bio diesel notice on their pump, but didn't think anything of it at the time.

Tank is nearly empty now, so I will be filling up tomorrow - albeit with Tesco's finest, as I have a 10p off per litre coupon - I'll endeavour to report back if there is any difference.

I reckon you've got dirty injectors and or a coked up turbo, try some tank additive and go for a nice 50 mile run where you can maintain 70 mph giving it hoofs every now and again until you see no black smoke coming out of the back anymore, p.s new air and fuel filters as well if you are over 40k.

Shouldn't be the case with mine DSG - week before last I drove from London to Edinburgh (not hanging about either), drove around whilst up in Scotland including a 130 mile round trip on one particular occasion, and then drove back from Edinburgh to London; all filters were renewed 7k miles ago.

I've got some Millers left in the boot however, so will put a slug of that in when I fill up tonight.

Will try the tank additive, its still been fine ever since and ive filled up twice now...never going to tesco filling up!! Cars had air and fuel filters done, got 70k on clock.

Any injector cleaner will kick in after 200 - 300 miles, then you will see the results. You will need to take it on the motorway, to clean all the crap that's built in the injectors.
